Ability to spy certainly limited by double-0 following Bond? (8)
I believe the answer is:
eyesight
'ability' is the definition.
(eyesight is a kind of ability)
'spy certainly limited by double-0 following bond?' is the wordplay.
'spy' becomes 'eye' (both can mean to see).
'certainly limited by double 0 following bond?' becomes 'sight' (I can't justify this - if you can you should give a lot more credence to this answer).
'eye'+'sight'='EYESIGHT'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for eyesight that I've seen before include "quality of viewing" , "View" , "Seeing faculty" , "Yes, eight required for vision" , "Purpose of certain organs" .)
